According to the ACB officials, complainant who has a tours and travel business had come to the record of the Nirmal Nagar police station four months ago in a railway ticket booking complaint case against him.

"Since then the three constables used to harass the victim and started demanding Rs 500 per month from him. The victim on Saturday registered a complaint with ACB," said a senior ACB official on condition of anonymity.

The official further added that, the constables told the victim to meet on Sunday with Rs 1,000 near Bandra railway station. "As soon as Ghadge arrived at the railway station at around 11 am, we nabbed him, while accepting the money. We later arrested Rane and Patel," he said. The trio would be produced before the court on Monday for police remand.
